Percutaneous Coronary Intervention Followed by Antiplatelet Monotherapy in the Setting of Acute Coronary Syndromes

Summary

Phase-3, randomized, multicenter, parallel-group study with blind evaluation of endpoints and intention-to-treat analysis. The general purpose of the study is evaluate the non-inferiority hypothesis for ischemic events and the superiority hypothesis for bleeding events resulting from platelet P2Y12 receptor inhibitors given as monotherapy in comparison with conventional dual antiplatelet therapy in acute coronary syndrome patients treated with percutaneous coronary intervention in the context of the Unified Health System in Brazil.
